At 5 P. M. the reading on the dry-bulb is 12°C and the reading on the wet bulb is 11°C. Determine the new relative humidity.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

correct answer:

b.(19,-2)

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
